Stem cells repair heart only early in life
from United Press International
Stem cells can replace dead heart tissue after a heart attack very early in life, but they lose that ability in adults, researchers say. Senior author Michael Kotlikoff, dean of Cornell's College of Veterinary Medicine, and colleagues at the University of Bonn said the study involving mice found undifferentiated precursor cells grow new heart cells in a 2-day-old mouse, but not in adult mice.
